µDose is a novel compact analytical instrument for assessing low level 238 U, 235 U, 232 Th decay chains and 40 K radioactivity. The system is equipped with a dual α/β scintillator allowing discrimination between α and β particles. The unique built-in pulse analyzer measures the amplitude of each individual pulse, its shape and the time interval between subsequent pulses. This allows the detection of pulse pairs arising from subsequent decays of 214 Bi/ 214 Po, 220 Rn/ 216 Po, 212 Bi/ 212 Po and 219 Rn/ 215 Po. The obtained α and β counts and four separate decay pair counts are used to calculate 238 U, 235 U, 232 Th and 40 K specific activities in measured samples through the use of radioactivity standards. The µDose system may be equipped with various photomultipliers and counting containers to assess radionuclide concentrations of samples of masses ranging between 0.4 g and 4 g. As a result, the user can customize the system to their needs and maximize the instrument's performance. The system is controlled by dedicated software with a graphical user interface and modules for system calibration, data visualization, specific radioactivity calculations and dose rate determination using the infinite matrix assumption.

“…This is shielded using lead with a significantly reduced 210 Pb concentration. The data are collected using a custom designed and made MCA (Tudyka and Bluszcz, 2011) that records the amplitude of each pulse as well as the time interval between the subsequent pulses. The schematic of the system is shown in Fig.…”

“…Radiocarbon laboratories using LSC do not apply this technique because it requires specialized electronics. In this work we use a dedicated multi-channel analyzer (MCA) (Tudyka and Bluszcz, 2011) capable of measuring both the amplitude and the time between the pulses simultaneously. This simplifies the procedure and reduces the cost significantly.…”

“…In addition, the height of the pulse is essential to measure because it can be used to estimate the radiation energy (radiation quality). Pulse processing can be used to measure the number and height of pulses [3][4][5][6]. Traditionally, pulse processing consisted of a detector, pulse shaping amplifier, and multichannel analyzers (MCA) [7].…”

“…As technology advances, analog to digital converter (ADC) devices are increasingly sophisticated to convert analog signals to digital rapidly. Therefore, many researchers use the fast ADC to build digital pulse processing (DPP) [3][4][5]8]. Like MCA, DPP is used to measure pulse height distribution (PHD).…”

A pulse height analyzer (PHA) is used to measure the frequency distribution of the signal output height of an event detector. However, the typical PHA algorithm has limitations in measurement; it cannot distinguish multiplet due to coincidence and singlet pulse. Coincidences will pile up the signals that make the pulse height value higher than it should be. Therefore, this study has developed a simple algorithm to calculate pulse height distribution with coincidence correction (PHA-CC). The developed algorithm firstly identified the coincidence pulse by considering its pulse width. The result shows that the developed algorithm could successfully distinguish multiplet and singlet pulses. The significance of pulse height distribution measured by the PHA-CC compared to regular PHA was also discussed in this paper.
